Styrofoam™ Brand XPS Insulation

Exceptional long-term performance. 

Low-GWP. Low embodied carbon. 

Since its invention in 1941, Styrofoam™ Brand extruded polystyrene (XPS) has built a rich, storied heritage as an innovative, sustainable building product – creating an entire insulation material category. Its unique closed-cell structure and rigid foam board technology enables XPS to meet core thermal, moisture, air and vapor performance requirements. 

 

The history of innovation continued in 2019, when DuPont began the process of reformulating Styrofoam™ Brand XPS Insulation to offer a low global warming potential (GWP) version. The transition was completed at the end of 2023. All sites in North America manufacturing Styrofoam™ Brand XPS Insulation now produce a low-GWP formulation signified by a new grey color.

More than meets the eye

EPS foam allows the intrusion of water over time.1 The closed-cell structure Styrofoam™ Brand XPS Insulation is the design choice for buildings that withstand the elements and the test of time.

Moisture
XPS structure absorbs significantly less water than EPS products

R-Value
XPS maintains R-value better than EPS when water is present1

Durability
Absorbed water can cause damage in freeze/thaw conditions
